Abstract

Field spectrometer plays a significant role in geological survey, agriculture, vegetation remote sensing, marine remote sensing and environmental monitoring. In the measurement of field spectrometer, the calibration algorithm and correlation processing of spectrometer are the key points and the research hotspots. In this paper, the methods of third-order fitting, linear fitting, polynomial fitting and normalization, respectively, to achieve the field of the spectrometer wavelength calibration and deal with the nonlinear correction algorithm. With the help of the processing ability of big data of the PC, a series of calibration algorithms and related processing functions of wavelength calibration and nonlinear correction spectrometer are designed. Experimental results show that the field in the spectrometer calibration accuracy, accurate to 0.3 nm wavelength measurement, nonlinear fitting precision to 1.029, these algorithms in field spectrometer with actual application, good results were achieved.
